Application Filed February 24, 1887, Serial No. lJJJll. (No model.)

To all whom it may concern,.-

Be it known that I, GEORGE WASHINGTON HADLEY, of Chieopee Falls, in the county of Hampden and State of Massachusetts, have in vented certain new and useful Iinprovonienis in GunSights, ofwhichthe following is aspeci eation.

My present invention relates to sights for rides; and the invention consists in certain novel features, hcrei nafter more full y described and claimed.

Figure lisa front elevation-of the sight coinpletc. Fig. 2 is a. vertical section ofthe saine on the line :v w ol' Fig. l. Fig. 3 is a face View of the eye-piece detaehcdr., .Fi g. 4 is a. rear face view ofthe rotatingdisk, shown detached; and

Fig. 5 is a transverse vertical section ol' the eyepiece and rotary disk enlarged, to more clearly show the details of construction; Fig. 6, a similar view, showing a slight modifica.- tiou.

rIlhis invention relates to that class of sights for rifles which are usually denominated peepsights,. and maybe considered as an improvement on the sight for which Iaient No. 172,465 was issued to me on the 18th day of January, 1876. f

The object of my present improvemcntis to provide a series ol' different-sized peep-holes, so arranged that either of them canA be used at will, and to so construct and arrange the disk in which these holes are formed that it can he applied to and used in connect-ion with the eye 4piece of iny former sight, or one Coin-)trueted on the same general plan, and so that the disk can be adj usted whenever desired without removing any of the paris.

It is well known to hunters and others using rifles that a larger peep-hole is desirable on a cloudy or foggy day than on a bright or sunny day, and vie-e versa. Itistliereforean object te harea sightthat can ne readily adj usted for different distances, and which can also be quickly adj usted. so as to use the dillerentsized peepholes. To accomplish these results, i make my improved sight as follows:

I make the leaf or standard A with a. slide, J, with rack and pinion' for adjusting the eye- Y piece l vertically, as shown in Figs. l and 2, and

as fully described in iny former patent. In the former ease the eyepiece I was provided with a single central peephole, c, which could not he varied in size. I nowlorni this eye-piece with a circular recess, f, in its front side, as shown in Fig. 3 and in section in Figs. 2 and 5, this reccssi nelnding within its boundaries the fixed peep-hole e, as shown. I then provide a disk, li., of a size to just lill this'recess, as shown in Figs. l and 3, and form in it a series of difier-v ent-sized holes, 1,2, 3, 4, 5, and 6, more or less in. number, as shown in Figs. 1 and 4, these holes being made in a circle coinciding with the stationary central hole, c, of the eyepiece I, so that by turning the disk h in its recess any -one ofthe holes in the disk h may he brought t, I secure a small round-pointed pin, n, as

shown in- Figs. 3 and 5, and inthe back ofthe disk h, I make a series ol" cavities, o, arranged .in a circle, as shown in Fig.. 4, of such a size as to permit the pin or projection a to engage therein when the disk is turned to the proper position, as represented in Fig. 5. It will of course bc understood that the relativeposition of these eaviticso and the pin n are arranged in relation to the peep-holes in the disk, so that when the pin a is seated in one of the cavities o one or" the peep-holes in the disk h will be directly opposite the central hole, c, ofthe eyepiece. Io enable the disk to he readily turned, it has a groove, fi, out across its face, asshown in Fig. I, and for convenience I provide a small dat key, It', (shown detached) the end of which can 1ne inserted in the groove and thus turn the disk, though it is obvious that it can be turned. by a knilehlade or any sinlilar implement. instead of the slot and key, a small pin may be made to project from the face of the disk, -by

which to turn it, if preferred; or by making 'he cavities o .in the disk I the nin a may be put through the disk h, with its ends projecting from opposite sides of lthe saine, in which cas l the inner end lwill serve as a stop by en' gagging in the cavities o, while its opposite pre jecting end may he used as a means i'or moving the' disk, as shown in Fig. d.

It will readily he seen that the spring; Z will permit the disk to rise slightly from its seat when turned, as it must to diseugage the pin n from the cavity o, in which it rest-s, and that as soon as the disk is turned far enough to bring the next hole in line the spring Wil1 eause the pin n to cuter the cavity which has been brought opposite, and thus lock and hold the disk in place until again moved. v

By this construction I produce a sight that 'can be adjusted vertically, and in which a different-sized peeplhole can be brought into use 'whenever desired without detaehing or changing any of the parts.

I am aware that disk-sights having a series of holes arranged to give different elevations have been described, and also that a disk having di'erent-sized holes has been described, and therefore I do not claim either of these broadly; but,

Havingr thus fully described my invention, what I do claim as my invention is@ sex-.1,955

concave eye-piece I, provided with a central hole, e, and a recess, t, for the disk h, and the disk h, provided with a series of diii'erent-sized holes, said disk being pivoted in the recess with its front face iush with the face of the eyepiece, substantially as shown andv described.

2. The combination, in a gun-sight, of the eye-piece I, the rotary disk h, provided with a series of different-sized holes, said disk being pivoted to t-he eyepiece by a screw, b, having a spring, l, mounted thereon, to press the disk against the eye-piece, and one of said parts being provided with a series of cavities, 0,'and the other with a piu, u, arranged to engage in lsaid cavities for the purpose of permitting the disk to be readily adjusted forward or back and holding it securelyin position when adjusted, substantially as shown and described.
